AWL ATTACHMENT FOR SHOE-CUTTING TOOLS.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed October 28, 1910. Serial No. 589,596.

To all whom it may concern:

Be it known that I, FRANK G. PAvnLno, a citizen of the United States,and resident of St. Louis, Missouri, have invented certain new anduseful Improvements in Awl Attachments for Shoe-Cutting Tools, of whichthe following is a specification.

This invention relates to improvements in an awl attachment for shoecutting tools, and has for its object a yoke which is arranged to bedetachably connected to the tool and an awl spring controlled andhingedly mounted to the yoke, the point of said awl being normally heldagainst the tool handle.

A further object of my invention is to provide an awl which can bedetachably mounted to the cutting tool, the same being normally out ofuse, but can be readily and easily manipulated by the thumb or finger soas to provide an indentation where and when desired.

Figure 1 is a perspective view of a shoe cutters knife and handleshowing my device in position on the same. Fig. 2 is a similar View toFig. 1 showing the needle of the awl attachment in extended positionready for operation. Fig. 3 is a detail perspective view of my improvedawl attachment. Fig. 4: is a detail perspective View of the needle madeuse of.

In the construction of my invention I provide a yoke or casing 5 soshaped and bent as to straddle any one of the knife bars 6, which aresupported in the handle 7. The yoke 5 has its prongs 8 bent inwardlyforming the ends 9, these ends passing over the edge 10 of the knifebars retaining the yoke in position as well as the end 11 of the yokeentering into the ferrule 12 of the handle, and by tightening down uponthe lower end 13 of the handle which is provided with internal screwthreads to correspond with like screw threads formed on the end of theknife bars, this feature not having been shown for the reason of thesame being old in shoe cutters knife con struction, the knife bars areclamped firmly against the blade 14, which has a tendency then to firmlyclamp the yoke 5 in position as designated in Figs. 1 and 2. The yoke isalso provided with a pair of projecting perforated cars 15 through whichis passed the supporting end 16 of the needle 17, both forming a part ofthe awl attachment. On the supporting end and between the ears 15 isattached a spring 18, its tendency being to normally hold the needle 17in contact with the handle 7 as shown in Fig. 1, so as to prevent thefingers of the operator from contacting with the point 19 while in thisposition, and in order to permit the 0perator to place the needle in anextended position as shown in Fig. 2, I provide a projecting strand 20which may be of a desirable shape, this strand 20 being in such positionthat the operator can whenever he desires to use the awl, by the mereplacing of his thumb on the strand 20, extend the needle and make therequired indentation, and immediately upon releasing the same the spring18 has a tendency to swing the needle back against the handle as shownin Fig. 1.

In the shoe trade, after cutting a vamp, it is necessary to indicate atwhat point and location the neXt portion of the upper is to be sewed.This mark of indication is made by pricking the leather, making smallindentations with an awl. Heretofore it has been found veryinconvenient, as separate instruments were used, whereas by my devicethe awl is in readiness and can be manipulated instantly.

Having thus fully described my invention, what I claim as new and desireto have secured to me by the grant of Letters Patent, 1s:

1. An awl attachment for shoe cutting tools, comprising a yoke, a needlehingedly mounted on said yoke in combination with a support againstwhich the yoke is attached, substantially as specified.

2. A device of the class described comprising a yoke, a needle carriedby the yoke, in combination with a tool handle to which the yoke isdetachably mounted, and means whereby the needle is normally heldagainst the handle, substantially as specified.

3. A device of the class described comprising a yoke, a needle formingthe awl proper movably mounted on said yoke, in combination with a toolhandle to which the yoke is detachably mounted, a spring for normallyretaining the needle parallel with the handle, and its point against thehandle, substantially as specified.

4:. A device of the class described compristhe thumb of the operator,substantially as ing a yoke, a needle forming the and proper specified.movably mounted on said yoke, in eombina- In testimony whereof, I havesigned my tion With a cutting tool handle to WhlCh the name to thisspecification, in presence of two 5 yoke is detachably mounted, a springcarsubscribing Witnesses.
